Description
Technical field
The utility model relates to a kind of coal bed gas drainage device, is specially a kind of magneto and drives full-automatic coal bed gas extraction machine.
Background technology
Coal bed gas is also called gas, be compose exist in coal seam with methane be main component, based on be adsorbed on matrix of coal particle surface, part be free in coal hole or the hydrocarbon gas be dissolved in coal seam water, be a kind of novel clean energy and high-quality industrial chemicals.In the region that coal resource is abundant, the coal bed gas resource be accompanied is also extremely abundant, and for the needs of safety in production, country proposes the regulation of first taking out and adopting afterwards for the actual state of producing, while making bygone Gu Yuan obtain controlling, obtain abundant coal bed gas resource.
At present, the collection technology mainly stress discern method of coal bed gas, namely utilize distinct methods that the gas pressure in coal seam is reduced, along with the reduction of gas pressure, coal bed gas becomes free state from ADSORPTION STATE through parsing, free state coal bed gas flows into coal bed gas well, until gas pressure is very low in coal seam by various crack.Because the method needs to carry out fracturing to coal seam early stage, extract the water being rich in gas be then separated so bleed to be actually, thus obtain required coal bed gas.So present domestic general exhaust plant and pumping unit are same set of equipment, i.e. beam pumping unit (hereinafter referred to as beam type air exhauster).
Beam type air exhauster is that one is made up of motor, reducer, crank-link mechanism, balance weight, down-hole exhaust plant.By motor, power is converted into low rotation speed large torque by reducer to export, drive crank-link mechanism, convert rotational motion is curvilinear motion by crank-link mechanism by power, then curve is converted into the rectilinear motion required for the pumping unit of down-hole by horse head.In China, beam type air exhauster system effectiveness only has 12% ~ 23% in general area, and advanced area is also less than 30%.The reason that its usefulness is lower causes because of itself structure design characteristic.Beam type air exhauster acceleration ratio in commutation process is larger.In whole machine, bar, pumping system, when the acceleration that commutates is large, air exhaust rod distortion is large.This distortion makes the characteristics of motion of piston in polished rod and pump produce very large difference.In most of the cases the elastic deformation of air exhaust rod decreases the traveled distance of piston, namely reduces the coefficient of fullness of aspiration pump.Beam type air exhauster makes the energy storage utilization rate of air exhauster improve mainly through regulating crank, but fail to change the feature of its property loading period change, the acceleration ratio of upper and lower 4 is larger, needed for beam type air exhauster, starting torque is larger in addition, realize long stroke more difficult, stroke can not be too low, increases type and air exhauster volume and weight can be caused excessive.
A large amount of extraction machines carries out work in inefficient district part, causes mass energy to waste.And this drainage device needs a large amount of manually constantly to go on patrol maintenance, and along with China's economic development, manpower and thereupon improving with the cost of accessory system of system disposition, reduce human capital cost-saving, improve automatic controlling level, also will become the whether outstanding leading indicator of evaluation system.
Summary of the invention
The utility model is high in order to solve the energy consumption existed in existing extraction machine technology, the problem that running cost is high, provides a kind of magneto and drives full-automatic coal bed gas extraction machine.
The technical solution of the utility model is, a kind of magneto drives full-automatic coal bed gas extraction machine to comprise support, platform, hound, console, balanced load, permagnetic synchronous motor, fixed pulley one, fixed pulley two, fixed pulley three, fixed pulley four, movable pulley one, movable pulley two;
Described support is provided with platform, platform is provided with console and permagnetic synchronous motor, fixed pulley one is provided with, fixed pulley two, fixed pulley three below platform, fixed pulley four, described wire rope two ends are fixed on below platform, are provided with movable pulley one between wire rope left end fixed point and fixed pulley one, and movable pulley one has balanced load, between fixed pulley four and wire rope right-hand member fixed point, be provided with movable pulley two, movable pulley connects air exhaust rod two times; Be provided with control system in described console, comprise PLC, PLC connects frequency converter, and frequency converter connects permagnetic synchronous motor, and PLC is also connected with human-computer interaction interface and wireless transmitter module.
Compared with prior art, innovation point of the present utility model is: (1), novel air exhauster system have employed permanent-magnetic variable-frequency synchronous motor Direct driver, instead of the mode of original threephase asynchronous and reducer group.Frequency conversion permanent magnet synchronous motor has a wide range of applications at low speed, high pulling torque, and security reliability is high.Simultaneously in energy-conservation, efficient, permasyn morot is better than traditional threephase asynchronous.In employing frequency conversion, make permagnetic synchronous motor more energy-efficient, protect other equipment in supply network simultaneously.(2) the application adopts the mode that movable pulley and fixed pulley combine, and original rocker motion is adjusted to counter weight type and moves back and forth, moment of torsion output characteristic curve is had and takes on a new look significantly.The characteristic curve of new system and the characteristic curve of permasyn morot match.Load generating period change in original structure, due to the cyclically-varying of load, power input to a machine must meet the requirement of system load peak value, makes the type selecting of motor bigger than normal, motor carries out under the operating mode of most of the time in inefficiency, causes energy waste.(3) employ remote control technology, add automaticity, decrease workman's use amount.This automation air exhauster energy saving of system is effective, is desirable air extractor.This automation air exhauster can realize Long-distance Control and monitoring, left unguarded automatic operation, reduces the intensity of workman's field work, ensure that the safety of workman, improve production efficiency.(4) structure is simple, easy disassembly.
